IMPROVEMENT IN REVOLVING FIRE-ARMS.

Speeiiieation forming part 0t` Letters Patent No. 116,559, dated July 4, 1871.

To all il'homI Vit may concern:

Be it known that I, FEEDERiC G. COCHRAN, of St. Louis, in the county ot' St. Louis and State ot' Missouri, have invented a new and useful Improvement in Revolving Fire-Arms; and I do hereby declare that the tbllowing is ai'ull, clear, and exact description thereof, which will enable, others skilled in the art to lmake and use the same, rete-rence bein g had to the accompanying drawing tbrining part of this specification, in which- Figure 1 is a side view ofa pistol to which my improvementhas beenattached. Figzl is a side view of the same with the barrel thrown up for withdrawing the cartridge-shells and loading, part heilig' broken away to4 `show the construction. y Fig. 3 is a rear-end view of the cylinder and retractor.

Similar letters ot'ret'erence indicate corresponding parts.

My invention has for its object to improve the construction and thereby promote the ellieieney ot' revolving tire-arms, more particularly the class ot' pistols designed to be carried conveniently in the pocket and adapted to use fixed annnunition alone. 'lo this end the invention consists in thel combination ot' certain devices for operating the cartl'i(ige-ejector, the salue being' so constructed and arranged as to be reliable in operation; also, strong, durable, not likely to get ont otorder, easily removed, and adapted to'lock or hold the cylinder securely in place or position for iiring, as hereinafter fully explained.

In the drawing,A represents the handle or stock; I3, the met-al lbreecli-bloek attached thereto land (l, the barrel oi" the weapon. An. arm, c', is formed on the rear end ot' the barrel, and hinged to the forwardly-proiecting arm, b', of the breech-block. The cylinder l) is constructed like those ordinarily used for utilizing fixed ammunition, and is arranged to revolve on a tube, E, which tits or is secured at its front end in the arm c of the barrel. The lever F is pivoted to the under side of the barrel, and provided with a hinged angle-link, in whose rear end swiveled a rod, l-I, that passes through the tube E, and is irlnly attached to the ejector-disk I. rlhe rear end ot' this rod isI conical or rounded to adapt it to lit in a` recess in the front wall of the breechblock. This recess is clearly shown in section in Fig. 2 of dia-wing. The ratchet-plate 'J is rigidly attached to the ejector-disk, so that, when acted on in the usual way by the mechanism ordinarily used for the purpose, it etfects the rotation ot' the cylinder by reason ot' the sen'xieircular notches in the periphery ot' the disk I iitting against the cartridges and, since the projecting rims ot' the cartridges reston the edges of the said notches, it will be seen that, when the barrel is swung' or tilted on its pivot, as shown in Fig. 2, the lever {"can bethrownlniek, and thusa-ll the lartridges simultaneously ejected. The barrel is held in its normal position for .tiring by a spring-catch, K, which inust be pressed down when it is desired to release the saine.

The oiice. of the recess in the breech-block above referred to is to prevent lateral movement of the rear end of the cylinder, and assist to hold`it rigidly in Vexact or proper relation to the barrel when the arm is being discharged.

Having thus described my invention, what I The lever F, angleflink (l, swiveled rod H rounded at its rear end, the ejector-disk I, and recess in the breech-block, combined and a-r- `ranged as shown and described.
